What is Difference between JpaRepository and CrudRepository in Spring Data JPA

What is Difference between JpaRepository and CrudRepository?

CrudRepository :-

  • CrudRepository provides mainly CRUD (Create, Read, Update and Delete) operation. 
  • The CrudRepository interface provides methods for CRUD operations, so it allows you to create, read, update and delete records without having to define your own methods.
  • Interface for generic CRUD operations on a repository for a specific type.
  • CrudRepository is base interface and extends the Repository interface.

public interface CrudRepository<T, ID> extends Repository<T, ID>

JpaRepository :-

  • JpaRepository provides CRUD operation as well as provides JPA related methods such as flushing the persistence context and delete records in a batch.
  • JpaRepository extends PagingAndSortingRepository which in turn extends CrudRepository.
  • JpaRepository add some more functionality that is specific to JPA.
  • The PagingAndSortingRepository provides additional methods to retrieve entities using pagination and sorting. 

public interface JpaRepository<T, ID> extends PagingAndSortingRepository<T, ID>, QueryByExampleExecutor<T>

Difference between JpaRepository and CrudRepository


When to use CrudRepository or JpaRepository?

  • CrudRepository mainly provides CRUD operations.
  • PagingAndSortingRepository provides methods to do pagination and sorting data.
  • JpaRepository provides some JPA related methods such as flushing the persistence context and deleting records in a batch.

Because of the above inheritance, JpaRepository will have all the functions of CrudRepository and  PagingAndSortingRepository.

So use JpaRepository if you want to use methods provided by JpaRepository and  PagingAndSortingRepository.

If you want to simple CRUD operation in application then use CrudRepository.

Flipping the Matrix HackerRank Solution in Java with Explanation

Java Solution for Flipping the Matrix | Find Highest Sum of Upper-Left Quadrant of Matrix Problem Description : Sean invented a game involving a 2n * 2n matrix where each cell of the matrix contains an integer. He can reverse any of its rows or columns any number of times. The goal of the game is to maximize the sum of the elements in the n *n submatrix located in the upper-left quadrant of the matrix. Given the initial configurations for q matrices, help Sean reverse the rows and columns of each matrix in the best possible way so that the sum of the elements in the matrix's upper-left quadrant is maximal.  Input : matrix = [[1, 2], [3, 4]] Output : 4 Input : matrix = [[112, 42, 83, 119], [56, 125, 56, 49], [15, 78, 101, 43], [62, 98, 114, 108]] Output : 119 + 114 + 56 + 125 = 414 Full Problem Description : Flipping the Matrix Problem Description   Here we can find solution using following pattern, So simply we have to find Max of same number of box like (1,1,1,1). And ...

Sales by Match HackerRank Solution | Java Solution

HackerRank Sales by Match problem solution in Java   Problem Description : Alex works at a clothing store. There is a large pile of socks that must be paired by color for sale. Given an array of integers representing the color of each sock, determine how many pairs of socks with matching colors there are. For example, there are n=7 socks with colors socks = [1,2,1,2,1,3,2]. There is one pair of color 1 and one of color 2 . There are three odd socks left, one of each color. The number of pairs is 2 .   Example 1 : Input : n = 6 arr = [1, 2, 3, 4, 5, 6] Output : 0 Explanation : We have 6 socks with all different colors, So print 0. Example 2 : Input : n = 10 arr = [1, 2, 3, 4, 1, 4, 2, 7, 9, 9] Output : 4 Explanation : We have 10 socks. There is pair of color 1, 2, 4 and 9, So print 4. This problem easily solved by HashMap . Store all pair of socks one by one in Map and check if any pair is present in Map or not. If pair is present then increment ans variable by 1 ...
